Information about the MEAN WELL HLG-185H-20AB
The MEAN WELL HLG-185H-20AB is the high-functionality flagship of the series, uniquely offering both manual and remote control options within a single unit. The "AB-Type" designation signifies its dual-control architecture, featuring internal potentiometers for fine-tuning the voltage (17–22V) and current (4.65–9.3A), alongside a sophisticated 3-in-1 dimming interface. This allows the driver to be seamlessly integrated into automated systems using 1-10VDC, 10V PWM, or resistance signals while maintaining local calibration control. Operating in dual mode (Constant Voltage + Constant Current), it provides a stable power foundation for complex LED street lighting, stadium lamps, and high-bay industrial luminaires. The IP65-rated metal enclosure ensures heavy-duty protection against environmental stress, while the advanced circuit topology delivers 93.5% efficiency. This energy-efficient, fanless design supports a lifespan of more than 62,000 hours even in demanding thermal conditions. To complement its professional-grade performance, MEAN WELL provides a comprehensive 7-year manufacturer warranty, making the HLG-185H-20AB a reliable long-term asset for any lighting infrastructure.
